PEEP can be harmful; high PEEP necessarily increases mean airway pressure and alveolar pressure, which can damage normal alveoli by overdistension resulting in DAD. A compromise between the beneficial and adverse effects of PEEP is inevitable. [citation needed] The 'best PEEP' used to be defined as 'some' cm H
Positive end-expiratory pressure (PEEP) is the pressure in the lungs (alveolar pressure) above atmospheric pressure (the pressure outside of the body) that exists at the end of expiration. [1] The two types of PEEP are extrinsic PEEP (PEEP applied by a ventilator) and intrinsic PEEP (PEEP caused by an incomplete exhalation).
P high — This is the inspiratory pressure (just like in pressure control). T high — This value is the number of seconds during the inhalation phase. T peep — Also known as the T low, this is the time allotted for expiration. FiO 2 — The fractional O2 percentage of the delivered air-and-oxygen mixture.
The pathophysiology of acute respiratory distress syndrome involves fluid accumulation in the lungs not explained by heart failure (noncardiogenic pulmonary edema). It is typically provoked by an acute injury to the lungs that results in flooding of the lungs' microscopic air sacs responsible for the exchange of gases such as oxygen and carbon dioxide with capillaries in the lungs.

NEW YORK − The man Dr. Gray Ballinger treated Wednesday for high blood pressure delayed care out of fear of immigration enforcement, the Queens primary care physician said. The man, whose wife ...
Optimal PEEP is used to maintain alveolar inflation and promote ventilation-to-perfusion matching. Jet ventilation has been shown to reduce ventilator induced lung injury by as much as 20%. Usage of high-frequency jet ventilation is recommended in neonates and adults with severe lung injury. [5]
According to a press release from SJSU, unusually high concentrations of nickel, manganese and cobalt were detected by SJSU’s Moss Landing Marine Laboratories. The heavy metals were seen in ...
The new findings suggest that eating high-fiber foods such as vegetables, beans and grains might help protect against harmful bacteria, he added. More research on fiber and health
